He took the medical book from Ning Caichen and flipped through it.

"This head-changing technique is actually a technique that combines mundane medical skills with magical spells. Guo Yancheng is just a mere mortal, but he can actually create such a vicious and magical technique. It is incredible." Ning Cai

The minister was somewhat impressed.

"But this person is really inhumane. Master, look at his comments. He used mortals to do head-swapping experiments at least dozens of times. In other words, at least dozens of people were killed by him like this.

Wow, this guy really deserves to be cut to pieces! But why did he do this? It’s really hard to understand.”

"What's so difficult to understand?" Su Yi sneered while flipping through the pages, "This guy has no spiritual roots, but he wants to become an immortal, so he wants to change himself into a body with spiritual roots."

Ning Caichen was stunned, took a breath and said: "That's crazy! But judging from his comments, he failed in the end! Fortunately, he died, otherwise God would be too cruel."

Moreover, he had already performed surgery on himself to remove a piece of his skull and replace it with this piece of soul-nurturing wood. At the same time, he injected undiluted "immortal blood" into the soul-nurturing wood to prevent unexpected situations and untimely needs.

Facts have proved that his preparation was effective. After he chopped off his own head, his soul was directly sucked into the soul-nurturing tree.

The ice phoenix essence and blood are fatal poison to the mortal body, but if it is just the soul, combined with the soul-nurturing wood, it has the effect of nourishing and strengthening it. This caused Guo Yancheng to die, but his soul became
